Fillerys Toffees was established in 1923 by a consortium of four investors led by Robert Harold Mayhew (1874 – 1965). The factory was located on Warwick Road in Greet, south Birmingham.
The site covered four acres by 1927, and due to increasing sales, 24 hour production was introduced from 1930.
Fillerys Toffees was incorporated as a public company in 1934. Herbert E Morgan was chairman. The company had an authorised and issued capital of £100,000 by 1935. Around 300 workers were employed.
Fillerys led the toffee industry as one of the most efficient producers by 1942. Fillerys targeted the higher quality market.
During the Second World War, most of the factory was given over to munitions manufacturing for the war effort.
Under a Government scheme to encourage industrial efficiency, Fillerys Toffees were produced under contract by Rowntree of York between 1942 and 1946.
The company had established nationwide sales distribution by 1949.
The end of sugar rationing in 1954 saw a boom in confectionery sales. Fillerys Toffees won a prestigious and valuable contract to supply confectionery for Marks & Spencer.
The sugar confectionery boom was over by the end of the 1950s, as increasing prosperity saw consumers increasingly switch to chocolate products. As a result, the industry began to consolidate in order to reduce costs.
Fillerys was acquired by J A & P Holland of Southport in 1960 to create the largest toffee manufacturer in Britain, and possibly the world.
Cavenham Foods acquired J A & P Holland in 1965. The Fillerys factory was closed down in March 1966, and production was transferred to Southport. The reason given was that the Fillerys factory did not have room for expansion. About 230 workers lost their jobs.
